8 weeks to go....lots of movement

We had another doctor's visit this week. All measurements were good. No further changes with the cervix and the growth measurements on the baby are right on. The baby weighs 3.9 lbs and the heartrate was at 128 bpm. The baby is moving around like crazy...I don't think it is just kicks...there is some rolling over or around going on in my belly. I am still really achy in my lower ab area. When you don't have much room the baby just hangs out in one area and it just happens to be down low for me. If I don't have to walk I am much better off....I move really slow when I do walk and of course I have the waddle going on. Don't get me wrong, but sitting isn't all that comfortable either. My tailbone starts to hurt after awhile. If I could lay down all the time, I would probably be okay. :) The good thing is I have only gained 9.5 lbs with this pregnancy. I can't imagine how I would be if I had a lot more extra weight on me. I met with my cardiologist last week and he said everything seems to be okay from a heart standpoint with the pregnancy. He has no concerns. I would have to agree with him as I haven't really experienced any problems as far as the heart is concerned. I have 8 weeks to go. Just taken it week by week now.
